Abstract

MÉTODO E DISPOSITIVO ILUMINADOR. Trata-se de um primeiro guia de raio toroidal que define um eixo geométrico de revolução e que tem uma pupila de entrada toroidal adaptada para formar uma imagem de luz que incide sob a pupila de entrada em um ângulo relativo ao eixo geométrico de revolução entre 40 e 140 graus e que também tem uma primeira superfície formadora de imagem oposta à pupila de entrada. Um segundo guia de raio toroidal define, adicionalmente, o mesmo eixo geométrico de revolução e tem uma segunda superfície formadora de imagem adjacente à primeira superfície formadora de imagem. Descrevem-se várias adições e outras qualidade dos guias de raio, que formam canais ópticos. Em um método, a luz que emana a partir de uma fonte entre 40 a 140 graus a partir de um eixo geométrico óptico é recebida em uma pupila de entrada com uma disposição de guia de raio que fica circulamente simétrica em torno do eixo geométrico ópitico. Nesse sentindo, a luz recebida é redirecionada através da disposição guia de raio até uma pupila de entrada substancialmente paralela ao eixo geométrico óptico.METHOD AND ILLUMINATING DEVICE. This is a first toroidal radius guide defining a geometry axis of revolution and having a toroidal entry pupil adapted to form a light image that falls under the entry pupil at an angle relative to the geometry axis of revolution between 40 °. and 140 degrees and also having a first image forming surface opposite the input pupil. A second toroidal radius guide further defines the same axis of revolution and has a second image forming surface adjacent to the first image forming surface. Various additions and other quality of the lightning guides, which form optical channels, are described. In one method, light emanating from a source at 40 to 140 degrees from an optical geometry axis is received in an input pupil with a radius guide arrangement that is circularly symmetrical about the optical geometry axis. In this sense, the received light is redirected through the ray guide arrangement to an input pupil substantially parallel to the optical geometrical axis.
